'RIM FOR- TIRES 0F MOTORrVEHICLE WHEELS.

Specification of Letters Patent.

Patented Dec. c, 1ero.

Application filed February 3; 1910. Serial No. 541,672.'

Be it known thatL, CHARLES B. Silvan', a citizen of the United States, residingat the city of Philadelphia, inthe county of Philadelphia and. State of Pennsylvania,

have invented certain new vand useful Imeach other to hold together against displacement, and at the same time so arranged as to provide' a handy and quick means to remove the tire-rim from the felly-rim of the wheel.

My invention embraces in constructive arrangement iirst, a tire-rim arranged to be slid onto the felly-rim of a motor vehicle `wheel; and second, a tire-rim with un.

threaded transverse taperlng recesses at suitable distances apart and a felly-rim with threaded surface complementally tapering recesses for respectively inserting threaded complementally tapering bolts therethrough to wedgingly tighten by drawing the tire and felly rims toward each other, thereby to firmly hold the same together against displacement, in the event of loss of extremital means, such as a bolt-head or a cotter or other pin.

The nature, scope'and characteristic features of my present invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof, in which- Figures 1 and 2, are vertical sectional l views through two different forms of a demountable tire rim for a' motor vehiclewheel,` embodying main features of my said invention.

Referring to the drawings 4 is an ordinary construction of wheel provided with a felly 5, and secured ...theretoin any Well known manner is a flanged rim 6, having at suitable distances apart threaded tapering recesses 7.

8, -is an 4infiated tire having a flanged inner clencher clamping rim 9, at suitable distancesgapart therein, provided with unthteaded complemental tapering recesses 10.

l1 is a headed bolt having square-shape, in cross-section, threads arranged along the same and the bolt made tapering to the opposite reduced threaded end and provided thereat with an opening 12, for a cotter or other pin 13, to be inserted therethrough from that end. Each bolt l1, is adapted to be entered through the nthreaded surfaced 'openings of the tire-rim and threaded surfaced openings of the-f-felly-rim, to wedgingly tighten by drawin'g'the said rims toward each other by turnings of the bolts 11, thereby to hold against possible displacement, the tire-rim to the felly-rim, whether a pin 13 becomes disconnected from the eX- tremity of a bolt, or the head of a bolt is lost. rlfhe form ofthe 'threads of the respective inserted bolts aiding to said results. At the same time by said arrangement` is permitted quick demounting of a punctured orhdilsabled inflated tire lfrom the felly of a w ee In the modified arrangement of Fig. 2, the

wheel 4, has a felly 5, provided with a flanged rim 6, and at suitable distances apart is provided therein threaded surfaced recesses 9, which are offset at 9". The inflated tire 8, has a clencher rim 9, as shown, having at suitable distances apart provided therein unthreaded surfaced recesses 10a, which are offset at 10b. 11a, is one of a series of threaded tapering shouldered and offset bolts adapted., when the inflated tire 8, with its clencher rim 9, is in operative position with respect to the felly rim 6, of the Wheel L1, of the said bolts 11a, being inserted through the tapering and offset openings formed by the tire and felly rims to ock by drawing'the two rims toward each other by wedging actions thereof.

It willbe observed that by. the `foregoing arrangements is obviated deflating of a tire prior to its removal from the'felly or of the infiating of the same after it\ is applied to the felly of the wheel. Y I do not claim introducing screw-bolts between the rim of a tire and the rim 'of a felly of a motor vehicle-wheel, as I am aware that such general arrangement is not lbroadly new, but what I claim as 'of my present invention. is, Wedgingly tightening by drawlng the tire-rim and felly-rim of a motor vehicle-wheel toward each other to thereby firmly hold the same together against displacement, by the wedging action of the bolts, whether a head of a screw-bolt is lost or a terminal means of the bolt, is displaced.-

.Having thus described the nature and ob- -jects of my invention, what I claim as new ed bolts arranged to engage the threaded portion of each of said openings to Wedg ingly tighten the rims together, against displacement.

2. In a motor vehicle Wheel, a tire having a clamping rim, a felly-rim, the respective' rims in position provided with oiset tapering openings, one portion threaded and the other Unthreaded land threaded bolts arranged to detachably engage in said openings to wedgingly tighten the rims together, l

against displacement.

In Witness whereof, Ihave hereunto set my hand 1n the presence of two subscribing witnesses.
